Graphing Lines and Analyzing Coordinates

The video tutorial explains how to graph three lines using their X and Y intercepts. It begins by identifying the intercepts for each line and then demonstrates how to plot these lines on a graph. The tutorial emphasizes the importance of scaling to avoid running out of space. After plotting, the video shows how to shade the regions based on the inequalities of the lines. Finally, it solves for the intersection points, labeled as points A, B, and C, by using algebraic methods to find where the lines intersect.
